Failed to Display Result error in Compliance Calibrator 5.2

Yes, first of all, we are going to upgrade to 5.3, and then 10, but for now I have this old version.

I ran an ad-hoc report in CC 5.2 as a background job. The job has completed and there is the icon to view the report. When I click on it, it shows me the report screen with no data on it, and at the bottom, it says, "Failed to display result".

I'm not sure what the reason is for this. Have you encountered this error before?

Thanks,
